Migration from Rpi1 -> Rpi2

[Skywatch]

I restored the image from auto back up.
The rpi1 used to run from usb, but image restored to uSD.
But only now have the SD card as the usb stick was needed for something else......
cmdline.txt was pointing to boot from usb stick (/dev/sda1).
So I changed it to boot from SD card by remaning cmdline.txt to cmdline.txt.old1
Then renaming cmdline.txt.old to cmdline.txt

I tried the card in another pi and it seems to mount OK = I get .....

/mount/usb0 - The host machine I believe.
/mount/usb1 - the SD card with the rpi1 image on.
/mount/xbian-boot-2442-D260 - The SD card with the rpi1 image on.
/mount/xbian-copy-lots of numbers/ - This also has the rpi1 image details on.

I hope that this makes sense, I am not fluent in Linux!
